APPARATUS FOR MOLDING LIQUIDS WHICH SOLIDIFY WHEN COLD.

Specification of Letters Patent. i Patented Mar. 29, 1910.

Application filed February 17, 1908. Serial No. 416,304.

To all whom it may concem:

Be it known that I, J AKOB WIDMnR-AoK- ERMANN, a citizen of Switzerland,residing at Zurich, IV Switzerland, have invented new and usefulImprovements in Apparatus for Molding Liquids which solidify when Cold,of which the following is a specification.

This invention relates to improvements in apparatus for molding liquidswhich solidify when cold, particularly such as cocoanut butter, and theobject is to provide means which facilitate the removal of thesolidified liquids from the apparatus. I attain this object by the meansillustrated in the accompanying drawing, in which- Figure 1 is alongitudinal section and Fig. 2 a cross section, and Fig. 3 a plan of anapparatus constructed in accordance with one embodiment of my invention.

Similar letters refer to similar parts throughout the several views.

Referring to the figures generally my proved apparatus consists of avessel a divided internally into a number of compartments 0 by means ofinwardly inclining.

walls I) which compartments are arranged in two parallel rows with aspace between them. Upon the bottom of the vessel a are arranged in thespace between the said two rows abutment pieces (Z against which bearthe lower parts of two movable walls 6 which close the said compartmentsinside of the apparatus.

In order to permit of pressing the walls e against the walls I; aturnable shaft, for instance a flat bar f extending along the walls 6 issuitably mounted in the space between the same. The part of this shaftoutside'the vessel a is bent at a right angle and serves as a handle forturning the shaft. If the sides of the shaft f are positioned oppositethe walls 6 the latter can be moved toward each other and the respectivecompartments 0 opened, that is to say widened.

When using the apparatus described, say for cocoa-nut butter, wrapperssay of parchment paper are inserted into the various compartments whichexactly fit the same.

The latter are then closed by the said mov-' able walls a by turning theshaft f and, thereby force its edges against the walls a and the warmliquid cocoa-nut oil is afterward poured into the said wrappers whichlatter will then tightly and evenly fit against the walls of thecompartments. In order to render the said wrappers at once impervious tooil, the cocoa-nut butter is'only heated to a temperature of about 2degrees C. above solidifying point (say to about 23' degrees C.) so thatthe cool walls and the wrappers will cause a thin layer of butter tosolidify at once, which prevents the butter yet liquid from soakingthrough. To cause the butter to cool as quickly as possible theapparatus described is preferably a of cocoa-nut butter simultaneously.

In practice a number of the molds described are placed side by side in atank containing waterfor cooling: By the time the last apparatus hasbeen filled, the contents of the one filled first will have solidifiedand such apparatus be ready for refilling, which renders the working ofthe in-' stallation continuous. The slabs or the like taken out, arepacked completely by closing up the side of the wrapper left open. Inthis manner practical as well as hygienic requirements are met, thetouching of the slabs or the like with the hands being prac-' ticallyentirely obviated.

I claim: Y

In an apparatus for molding in wrappers: liquids which solidify whencold, two series 95 of molding compartments arranged parallel to eachother, each of the said compartments comprising an open side and twowalls diverging'toward the said open side,

a movable wall for each of the said series 100 of eompartments and atunable bar bename to this specification in the presence tween andbearing a ainst the whole length of two subscribmg witnesses.

of the said loose we to press and lock the same a%ainst the edges of thesaid diver AKOB WmMER-AQKBRMANN. 5 ing wal s, all combined substantlallyas and Witnesses:
